| 摘 要： | 分别使用原位掺杂的方法和溶胶-凝胶自燃烧的方法制备了聚苯胺微管以及纳米NiFe2O4晶体；并对聚苯胺微管以及聚苯胺／NiFe2O4和石蜡的复相粉体在8～12GHz频率范围进行了复介电常数和磁导率的测量。结果表明，聚苯胺微管在测试频率范围内为介电损耗材料，当纳米NiFe2O4晶体加入到聚苯胺和石蜡的混合体系时，聚苯胺／NiFe2O4和石蜡的复相粉体混合体系在测试频率范围内同时具有一定的介电损耗和磁损耗，并且其混合体系的微波吸收性能高于单独加入聚苯胺时的微波吸收性能。

| Abstract: | Polyaniline canaliculus and nano-sized NiFe2O4 crystalline are prepared by using in-situ doping method and sol-gel auto-combustion method respectively. The electromagnetic properties of the compound, which consists of polyaniline canaliculus,nanosized NiFe2O4 crystalline and paraffine,are studied. It is shown that polyaniline is a dielectrical dissipation material in the microwave electromagnetic experiment. When doping nano-sized NiFe2O4 crystalline to polyaniline canaliculus, it is found that both of the dielectric loss and the magnetic loss exist in the measurement range, and the reflectivity of the compound is higher than that of polyaniline canaliculus system. |
